To ALL when 1T MAY rcoNennN: Y

f Beit known that D. STAFFORD, deceased, did, during his lifetime, invent a new `and improved Cultivator, and that 1', ELTZA STAFFORD, of Deeatulg'ntho county of.Macon, and -State of Illinois, executrixof 4the-said y A` l). S S'riirronn, deherehy' declare that the following is a full, clear,"a11d exact description thereof, which will enahle others skilled in -tlie art-to niake :ind use ,the same,`ret`erenee being had to the accompanying drawings,y forming part of this specification', in whiehl Figure 1 is a side sectional VView-of the invent-ion, taken in the line n.: eyig. 2. Figure 2, a plan or top yview of the same.

Similar letters of're'fereuce indieatelike-parts` n This invention relates to a new and improved cultivator, of that class r-'hichnre designed for cultivatingcrops grownj in. hills or drills. The invention consists in a novel and improved arrangement of crankqxxles whereby the ploughs may be adjusted higher or lower, so as to plough more or less deep, asrequired, and all the pioughs of the machine graduated so as to plough an equal depth. The invention further consists in a novel nrrangementof the plough-standards, and in va peculiar shape of the ploughs, whereby the latter are prevent-ed from'cloefvnnr or choking;

A represents the frame oithe'l'aeliine, havipg'the driverss'eatfll on its rear end, and a draught-pole, O,

r attached to it by a pivot-holt, e, 'tofecilitate the turning or guiding ofY the machine. The frame A is mounted cn two wheels the axles E E of which are of crank forro and fitted 'in suitable pendent bearings b'a-ttachcr l I to `the fframeA. These axles E E are independent', of each other,=and euch has a lever, F, attached, which t lovers are within convenient reach ofthe driver-on seat B, and are by the side'of upright semieirculer bars G,

attached one to each side of the frame A, and provided with pins or projections'e', or hoth, by which the levers l l" muy be retained at any desired point within the scope of their moreinent, and the ploughs securedat a 'greater 1 or less height, aecordingvto the depth of'fnrrow required.- H represents the plough-st`andards, the upper ends i ot' which are piifeted-ro the frame A, as shown at d. These standards are ot curvedform, as shown 'clearly in` fig. 1, and to the lower ends of the standards ploughs I are attached. These ploughs are'of oval or elliptical form, and curved so as to cast the earth either towards or from the plants, es may bedesired. There are our ploughs in all, two atczireh side, `ot' the machine, the two front ploughs boing,r nearer together than the `two rear ones, and the two standards IjI H, at eaehside of the machine, are connected bye chain, J', and these chains "il l pass around pulleys K- K,'seeured to the front part ot' the frame A. By this arrangement the two ploughs fat cach side ofthe machine are'allowcd to equalize themselves, one plough in case 4oiumeeting with anob'struction- .being made to pull against the other. It `will beseen that in consequence oi" the plcugl1-standards H being attached directly to the frame A, all the ploughs will, as the frame A is raised or lowered, 4be adjusted higher or h lower'simultaneonsland all moved precisely the same distance; hence the ploughs will. allpenetrate into the earth the saine depth. By referring to fig. 1 it'will he seen that thestandards H are curved backward just l above the ploughs. This curvature prevents the earth from adhering to Vthe standards, es it must drop off `by virtue of its own gravity, there boing nothing to held it, no ledges, shoulders, or angles. The machine is sup plied with the guards K', to prevent thefront ploughs throwing or casting elods of earth upon the plants, These guards, however, are not new, and may be seen in incany machines.

Having thus described my invention, what I claim as new, andfdesire to secure by Letters Patent, is-

The pivotod curvedplongh-standards H connected ,by the chains J. suhstantially as and for the purpose' spe'ified. l ELIZA SlAFFOlitD.V Witnesses:
